Scientists in the Energy Department's Natural Renewable Energy Laboratory calculate that wind turbines produce an average of 0.4 ounces of carbon dioxide per kilowatt hour generated, over their lifetime. That includes emissions from manufacturing. Natural gas produces 58 times more carbon dioxide — at least 22.6 ounces per kilowatt-hour.
